LEAFHOPPER SUBFAMILY NEOCOELIDIINAE — KRAMER 265 



Chinaia was recently revised by Kramer (1959). A habitus drawing 

 of a typical Chinaia can be seen in figure 113. 



Deltocoelidia Kramer 



Deltocoelidia Kramer 1961, p. 238. Type of genus Deltocoelidia maldonadoi 

 Ivramer by original designation. 



Description. — Without carina separating face and crown. Shape 

 of crown in dorsal view bluntly angular. Ocelli located on anterior 

 margin of crown. Head including eyes about as wide as pronotum, 

 which is broadly indented on posterior margin. Antennae about as 

 long as total length of body including forewings. Venation of fore- 

 wings obscure except apically. 



Ground color stramineous with contrasting markings on crown, 

 pronotum, and forewings in form of stripes and spots. 



Male genitalia: Male plates solidly fused and appear as single plate 

 on venter of genital capsule. Both pygofer and anal tube simple. 

 Connective Y-shaped and poorly sclerotized. Aedeagus slender, 

 recurved, and with paired lateral processes. 



Discussion. — The single leafhopper at present referable to this 

 genus is the type-species, Deltocoelidia maldonadoi Kramer, known 

 only from Venezuela. Illustrations of the male genitaha appeared 

 with the original description. 



Xenocoelidia Kramer 



Figures 38-44 



Xenocoelidia Eo-amer 1959, p. 30. Type of genus Xenocoelidia youngi Kramer 

 by original designation. 



Description. — Without carina separating face and crown. Shape 

 of crown in dorsal view rounded or subangular. Ocelli located on 

 anterior margin of crown. Head including eyes either as wide as 

 pronotum or slightly narrower. Posterior margin of pronotum 

 broadly and very shallowly indented. Antennae as long as total 

 length of body including forewings. Venation of forewings obscure 

 except at tip. 



Ground color ivory to yellowish with or without contrasting mark- 

 ings on crown, pronotum, and forewings. 



Male genitalia: Valve lacldng. Male plates fused at least basally, 

 at times for most of length. Pygofer with or without ventral tooth 

 but always with terminus slightly thickened and bearing setae. Anal 

 tube simple. Connective Y-shaped and closely associated with aedea- 

 gus but joint between them flexible. Style long with mesal curvature. 

 Aedeagus slender and broadly U-shaped in lateral view with apical 

 elaborations.
